Designer Ronen Spector designed this SPiNe - Secure your city Bicycle. The project deals with urban bicycles and answers the need to secure them in a fast, easy and effective way. The mechanism of the bicycles allows, on one hand, stable riding in the city and on the other hand, the use of a frame part as a locking mechanism. Using this mechanism for the securing bicycles does not require carrying any additional measures. The thought is that as the spine provides stability for the body and damaging it will damage the body strength, so too damage to the locking mechanism, which is a part of the bicycle frame, will damage it's structure. Designer has designed this project as part of his studies at Shenkar college under the guidance of the head of industrial design department, lex Padwa.
